The humidity of the farm is high: in summer, the temperature is mainly cooled by water injection, and the indoor humidity can reach 85%. The high-humidity use environment has also increased the requirements for decoration materials, and the pig house needs to maintain a high room temperature all the year round. The temperature of the pig house is 28~30 degrees Celsius; the temperature of the farrowing room is 37.6~39.5 degrees Celsius, and the temperature is also higher than that of the general building environment. The volatilized feces are mainly ammonia gas, which enters the interior through the surface pores of the decoration products, and also has certain corrosive properties. Under these requirements, the materials that need to be selected during the decoration of the farm have become more stringent, and the anti-corrosion and purification coated steel plates produced by Himei Metal have undergone a number of experimental tests, which can easily cope with the environment of the farm and improve the service life. Fields, electronic workshops, food factories, etc. have applications. Interested customers can call 138-1258-7955.
